Description
Rollei RPX 25 — 35mm x 30.5m Black & White Bulk Film
The Rollei RPX 25 is a low-speed, ultra-fine grain black and white negative film engineered for photographers who demand the highest standards in resolution, sharpness, and detail. With an exceptionally low RMS granularity of just 8 — significantly below comparable films — the RPX 25 enables virtually unlimited enlargements without visible grain, making it the benchmark choice for landscape, architectural, and studio photography.
Available in a 35mm bulk roll of 30.5 meters, the RPX 25 is ideal for photographers who load their own cassettes and require a consistent, high-quality emulsion for traditional darkroom work or high-resolution digital scanning workflows. Its polyester base ensures dimensional stability and durability across demanding shooting conditions.
Film Specifications
Key Features
Ultra-Fine Grain — RMS 8
Exceptionally low granularity of RMS 8 — well below the typical RMS 9.5–10 range — for smooth tones and invisible grain even at extreme enlargements
Very High Resolution
Optimized emulsion structure resolves the finest details with exceptional clarity, ideal for large-format prints and high-resolution drum scans
Panchromatic Sensitivity
Full panchromatic response ensures accurate tonal reproduction across the entire visible spectrum from deep shadows to bright highlights
Polyester (PE) Film Base
Dimensionally stable polyester base resists curling and stretching for consistent flatness in both darkroom and scanning workflows
Bulk Roll Economy
30.5-meter roll allows photographers to load custom-length cassettes, significantly reducing per-shot cost compared to pre-loaded cartridges
Darkroom & Digital Compatible
Equally suited for traditional chemical enlargements and modern high-resolution flatbed or drum scanner workflows
Low ISO — Maximum Image Quality
ISO 25 speed prioritizes image quality over sensitivity, delivering the finest tonal gradation and micro-contrast available in 35mm film
Ideal Shooting Scenarios
Best suited for landscape, architecture, still life, and studio photography where a tripod is used and maximum detail is the priority
